📋 Teacher notes

  • •vx is constant throughout — no horizontal force acts on the projectile.
  • •When h₀ > 0, the optimal angle for max range drops below 45°.
  • •Complementary angles give equal range only when launched from ground level.
  • •Platform height slider — drag it up to simulate a cliff or tall building.
  • •Use the gravity slider to explore projectile behaviour on the Moon (1.6 m/s²) or Mars (3.7 m/s²).
